In benzene, ninhydrin undergoes electrophilicsubstitution at C2 of 3,5-dimethoxyaniline, leading to the indeno[1,2-b]indole (7), which can in turn be transformed into the fused indolederivatives (9), (17) and (19), the indolenines (15) and (16), the indolone (18), and the dihydroindole (8). The corresponding reaction in water undergoes electrophilicsubstitution at C4 to give compound (11)
